Official: BlackBerry Storm2 9550 OS 126.96.36.1993 from Verizon Wireless
It wasn’t too long ago that OS 188.8.131.523 officially released for TBayTel. Now if you’re on the Verizon network you too can get this OS if you haven’t already. It should start to get pushed to your device for OTA install.
If you haven’t already been prompted to install OTA you can download the full OS and install using Desktop Manager or another loader.
